TensorFlow Installation

In this article

TensorFlow is an open-source platform for machine learning and deep neural network training, developed by Google. With TensorFlow, you can create, train, and utilize complex neural networks using a user-friendly API in Python.

This platform supports both traditional machine learning algorithms, such as linear and logistic regression, as well as more advanced architectures, including convolutional neural networks (Convolutional Neural Networks, CNN) and recurrent neural networks (Recurrent Neural Networks, RNN).

TensorFlow Installation on Linux

This instruction is suitable for the following operating systems: Ubuntu 22.04, and verified for Python versions: Python 3.10.

Note

If you plan to use GPU acceleration, please install NVIDIA drivers and CUDA according to this instruction.

  1. Install Python:

    sudo apt install python3.10

    In Ubuntu 22.04, this version is installed by default, so we do not recommend installing a newer version.

  2. Installing system libraries for TensorRT:

    wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update
sudo apt-get install tensorrt

  3. Create a virtual environment for Python:

    python3 -m venv venv

  4. Activate the virtual environment:

    source venv/bin/activate

    After successful activation, the prompt will include the name of the virtual environment in parentheses:

    (venv) user@49069:~$

    Note

    You can create as many virtual environments as you like and install different libraries (including simultaneously, but sometimes this may cause conflicts).

  5. Installing bindings for TensorRT:

    python3 -m pip install wheel
python3 -m pip install --pre --upgrade tensorrt

    To verify the installation, we can run Python in the console and execute the following script:

    import tensorrt
print(tensorrt.__version__)
assert tensorrt.Builder(tensorrt.Logger())

    Upon successful installation, the output will be:

    (tensorflow) user@49069:~/gpu$ python
Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorrt
>>> print(tensorrt.__version__)
10.0.0b6
>>> assert tensorrt.Builder(tensorrt.Logger())
>>> import tensorrt_lean as trt
>>> print(trt.__version__)
10.0.0b6
>>> assert trt.Runtime(trt.Logger())
>>> import tensorrt_dispatch as trt
>>> print(trt.__version__)
10.0.0b6
>>> assert trt.Runtime(trt.Logger())
>>>

  6. Installing TensorRT version 8.6.1.

    wget https://developer.nvidia.com/downloads/compute/machine-learning/tensorrt/secure/8.6.1/tars/TensorRT-8.6.1.6.Linux.x86_64-gnu.cuda-12.0.tar.gz
tar -xzvf TensorRT-8.6.1.6.Linux.x86_64-gnu.cuda-12.0.tar.gz

  7. Installing the TensorFlow library with GPU support:

    pip install tensorflow[and-cuda]

  8. Exit the virtual environment:

    deactivate

  9. Create a script to run TensorFlow:

    echo '#!/bin/bash' > tensorflow.sh
echo 'source venv/bin/activate' >> tensorflow.sh
echo 'export CUDNN_PATH=$(dirname $(python -c "import nvidia.cudnn;print(nvidia.cudnn.__file__)"))' >> tensorflow.sh
echo 'export LD_LIBRARY_PATH=$CUDNN_PATH/lib:/usr/local/cuda/lib64' >> tensorflow.sh
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/TensorRT-8.6.1.6/lib' >> tensorflow.sh
chmod +x tensorflow.sh

Running TensorFlow

To run TensorFlow in a virtual environment with specified library variables from the root directory of your home directory, use the command:

. tensorflow.sh

Verifying TensorFlow Installation

To verify the functionality and GPU support of the library, launch the following Python program in the console:

import tensorflow as tf
print(tf.reduce_sum(tf.random.normal([1000, 1000])))
print(tf.config.list_physical_devices('GPU'))

Upon successful installation, you will receive an output similar to this, displaying your GPU usage.

Additionally, you can download and run the test Python script for training a neural network 2c_nn_mnist_customtrain.py from this GitHub repository.

Upon completion of its execution, you should receive an output similar to this:
